Hi, I just recently moved to Germany (PCS'ed) and I have the x910bt, I would like to put European maps on it, but what cost will this come to the unit itself. Can I undo the mod's when I return stateside? and how well do the maps work I don't really want to have some half ass'd crap on there. Anyways any help or links pointing me in the right direction would be helpful,
